Caterpillar has transformed from a traditional construction equipment maker into an AI market darling, with shares surging as the company capitalizes on data center infrastructure demand. The 100-year-old industrial giant, known for its iconic yellow machinery, now generates record revenue through energy and power systems that support AI-driven infrastructure.

In 2024, Caterpillar reported $67.6 billion in full-year sales and $19.06 adjusted earnings per share, both all-time highs. The company's energy and transportation segment surpassed its construction industries business for the first time, generating $28.8 billion versus $25.5 billion. With a record $51 billion order backlog up 70% year-over-year, Caterpillar projects 5-7% revenue growth for 2026.

Rather than developing AI technology itself, Caterpillar supplies critical equipment including turbines for on-site power, generator sets for backup, and integrated microgrid systems combining traditional energy with renewables. Morningstar recently raised its fair-value estimate for Caterpillar shares into the low-$600 range, citing improved guidance and stronger end-market demand. While fundamentally cyclical, Caterpillar has positioned itself as a surprising beneficiary of the AI boom through its essential infrastructure role.
